380 Def @ Level 9

Hi there!
I rerolled a warrior last night and i did the Midsummer dailys just for EP. Because i don't intend to gather 300 blossoms or whatever I just buyed some of the Midsummer Bufffood - 20 Hit and 20 Def.

I used them and went questing and then I saw something strange: I had 380 def. 40 regular + 340. The only buffs I had were the Bonfires Blessing (fire dmg on hit) the Ribbon Dance (10% XP) and the two bufffoods. (and rank 1 AP-shout)

maybe its possible to abuse this with lvl 70?

EDIT: and yes, i died once and buffed myself again after ressing and i had the 380 def again.
